After being away from Halo 5 for a good couple of months, and coming back to play in Warzone Firefight (firefight was my favourite mode in ODST and Reach), I did notice some problems with it, and some of the things was already said by the Act Man on youtube, but I think it needs repeating.
The fact that the player that gets the last hit on a boss, legendary enemy, or Mythic enemy gets the points seems unfair, now I am not sure if this is still a problem with regular Warzone, but I have gotten from 7th to 2nd place all because I got the killing shot on the boss, even though 3 or 4 people were doing the most damage to them.
The range of some weapons baffles me, I was flying a Wasp and I was getting shot from an Elite on the ground, and while I was moving to evade, he was still getting every shot, also I noticed that the needler fire from the boss Grunt can catch a Banshee doing Ariel moves to dodge them.
The health on Warden Eternal is insane, I was in a match, and in the final round, me and two others were in Scorpion tanks, shooting him, and it took a good deal of time to kill him.
The invincible Phantoms are one of the worst things, especially since until the enemies jump out of the Phantom, they too are invincible, so when there are two dropping enemies at the same time, and you are in a Wraith, you are basically dead since the torrents will destroy you.
Now there are probably more problems that I have forgotten, but these are the ones I remember, what are the problems you guys have seen?
